GALVANIC BATTERY.

Patented Sept. 22, 1914.

Application filed July 10, 1913. Serial No. 778,280.

To all whomjt may concern 'Be it known'that 1, CHARLES B. SOIIOEN- MEHL, citizen of the United States, and resi dent of lVaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in a Galvanic Battery, of which the iollowing is a specification.

My present invention refers more particularly to a high resistance or track circuit battery such as are employed and adapted or railway signal work.

The object of the invention is to provide a simple and inexpensive form of battery which may be readily assembled, charged and connected in a series and renewed from time to time with comparatively little labor and trouble; also to provide a battery that will be particularly well adapted for use in one open top or uncovered form of jar; to design the elements so that they may be readily supported at proper distances apart one within the bottom of the jar and the other from the top portion, and especially to provide a novel form of suspending means for the upper zinc or positive element whereby it will gradually settle down and maintain its same active position and insure a uniform internal resistance, and further to provide a suitable insulated guideway for the circuit wire connection made from the lower or'positive element.

The invention further resides and consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.

Similar characters of reference will be found to denote like or corresponding parts throughout the several figures of the accompanying drawings forming a part of this specification and upon which Figure 1,

shows a central vertical longitudinal section through my improved form of battery complete. \Fig. 2, is a detached plan view of the supporting device and positive element together with guide for field wire of negative element, and, Fig. 3, shows a detail side view of a portion of the positive element and support as they would appear after be ing in operation for a time.

Referring in detail to the characters of reference marked upon the drawings A represents a battery jar which may be of the usual or any preferred construction and B the negative elect-rode which as will be noted comprises a sheet metal container C filled with loose oxid of copper scale D and provided with a perforated cover portion E. The container is of a round fiat shape having suitable beaded annular seams on its top and bottom edges and formed of the connecting ed e portions of the metal. This container as s own is designed to rest upon the bottom of the inside of the jar. The field wire connection F is secured to the central portion of the container and preierably passes through a suitable hole in the top or cover portion E and is made fast to the central portion G of the bottom of the container by nuts Gr arranged on both the inside and outside of said bottom, so that when supported by the wire in handling, the container will be supported centrally and thereby hang horizontally of handling.

The positive element H is of the usual cylindrical zinc construction having an attached field wire I that is riveted, sol ered and sealed to the side of the element as shown at J and is disposed upward out of the topof the jar for connection to an adjoining battery or for line connection as occasion may require. The support K for the said positive element is formed of two iron wires the central portions L of which are twisted together to form a rigid connection and a central hole M to receive a porcelain sleeve N through which the before mentioned field wire F is threaded as shown in Fig. 1. ,The end portions of the supporting wires are disposed outward and then turned up substantially parallel to each other and have their extremities turned over to form supporting hooks O that rest upon the upper edge portion of the jar. This construction, as will be apparent, produces an inexpensive wire support which may be readily set in place or removed and serves to support the positive elements below the solution line a of the battery and likewise provides a reliable support for the porcelain sleeve central of the lower edge in a way to insure ease portion of the Zinc so as to allow the wire .the. battery and yet without contacting with the said zinc. This construction obviously permits the parts to be quickly assembled, placed in or removed from the jar, which of course, is very desirable, and convenient when it comes to renewing the elements,

ments in substantially their which operation can be performed by an attendant withoutthe necessity of getting his hands soiled by the solution. In this respect it will be seen that he simply needs to take hold of the central wire F and lift it up and out which strips the jar of both elements and the support. The new elements can then be set in place with respect to the said support and the new assemblage again set in the jar.

It will be seen that the lower annular edge ofthe Zinc normally rests upon the radially disposed horizontal portions of the wire support and is therefore nearest to the negative element and is obviously first eaten away around. this edge portion. Also owing to the fact that both said wires and Zinc are submerged in solution, local action takes place between the wires and zinc at the point of this connection. This causes the zinc to be eaten away at this point slightly in advance of the remaining body portion of the zinc and allows the zinc to settle as it is eaten away, see Fig. 3. This obviously maintains the body' of the operative eleoriginal relative position with regard to each other and therefore maintains a uniform internal resistance of the battery throughout its period of operation.

Having thus described my I claim and desire to secure cut is 1. In a battery of the class described, the combination of a negative element comprisin g a fiatsheet metal container having a perforated cover, a filling of oxid of copper invention what scale within said container, a wire connect ed to the central portion of said container, a positive element, a wire support for the same and formed of two U shaped wires having hook like end portions for attach ment to the top edge portion of a jar and twisted together to form a central socket, a sleeve seated within the socket to guide the field wire for the negative element, the said support being suspended from the edge portion. of the jar and in a way to bring the positive element below the solution line.

2. The combination of an electrode support for supporting a zinc below the solution line and formed of substantially U shaped wires which carry a zinc electrode thereon; the central portions of said Wires by Letters Patbeing connected and shaped to form a oentery and having its end portions disposed tral socket to guide a field wire of the batoutward and upward and with hooks formed upon their extremities for attachment to the edge portion ranged to insure the suspension of the major portion of the support within a battery jar' and below the solution line.

of a jar, the whole ar 3. A battery element support formed of two pieces of metal the central portions of which are twisted together for connection one with the other and to form a central socket therein, the free end portions of said wires being disposed outwardand upward with hooks formed upon their ends for attachment to the edge portions of a battery ar to insure the suspension of the support within the jar and below the solution line, and a guide sleeve mounted within the socket. 4

4. A battery element support formed cl two U shaped wires and comprising a series of hook portions for the engagement of the 1 top edge of a battery jar and comprising an intermediate body port on'arranged below the level of the outer and hook portions to support an annular zinc and having said intermediate portions suitably connected together and. forming a guide hole through which a wire may be threaded, the whole arranged to support an elementwithin the upper portion 0 a jar, but of the solution line.

5. A battery element support formed or pieces of wire and a porcelam sleeve the said sleeve being supported connected portions of the wire which eneirbelow the level by the intermediate clethe sleeve and are twisted one about the other, the extended portions of said wires beingdisposed outward to support the battery elementand the extremities of saidwire' being disposed upward form hooks to engage the top edge of the jar in a way to suspend the element within the solution below the top'line of the same. i
